Yuegong is the purchasing manager of a famous elevator manufacturer in the Yangtze River Delta. Recently, he found AOQUN and asked about the tensile strength of the brush. Because the brush produced by the Anhui factory has a filament loss phenomenon, the filament loss will not only reduce the safety performance, but also reduce the customer's brand image. During the period, six escalator safety brush suppliers were also changed. The phenomenon of filament loss has not been completely solved. It is known that the AOQUN is an escalator safety brush supplier, so Yuegong asked whether it can meet the quality requirements.

After understanding the concerns of Yuegong, AOQUN business staff Roger told Yuegong: AOQUN has been professionally escalator safety brush supplier producing the brush on the escalator for 10 years. The factory strictly follows the ISO:9001-2015 quality management system standard to do the incoming inspection, sample inspection, factory inspection. And according to the company's internal stirp brush product quality inspection standards to do a good pull test, to ensure that the brush's tensile strength is required to reach more than 6kg, the brush does not loss filament. In order to further deepen the trust of Yuegong, he also mailed a sample for him to conduct tensile tests and other tests.

On the third day, Roger received a feedback from Yuegong, saying that, “I have already seen the sample and personally tested the sample tension, which was very satisfactory. At present, AOQUN will be introduced to the supplier system as the escalator safety brush supplier. After the system is finished, it will immediately place an order for the brush of 20 escalators. If there is no doubt that the subsequent brush orders on the 1000 escalators will be placed on AOQUN soon.
